Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'influence' (влиять).
- The Russian direct equivalent 'надувать' can be literal (надуть шар) and figurative (надуть цены), but the figurative use in English is broader, applying to abstract concepts like 'ego' or 'statistics'.
- 'Inflate' is not typically used for 'to cheat/swindle' as 'надувать' can be in colloquial Russian.
Common Mistakes
- Incorrect: *'The company inflated their success.' (Better: 'exaggerated' or 'overstated' unless referring to specific metrics).
- Incorrect: *'He used a pump for inflate the ball.' (Correct: 'to inflate' or 'for inflating').
- Confusing 'inflate' (active process) with 'swell' (often a passive process, e.g., from injury).
